Efficient pelletizing and granulating equipment

Abstract

The invention discloses efficient pelletizing and granulating equipment. The equipment comprises a supporting frame, wherein a feeding hopper is arranged on the supporting frame, a fixed roller and afloatable roller are arranged on the supporting frame, a discharging opening is formed in the bottom of the feeding hopper, blocking frames enabling the inner ends of the fixed roller and the floatable roller to be closed are fixedly connected to the inner end surfaces of the fixed roller and the floatable roller respectively, forming holes are formed in the fixed roller and the floatable roller in a penetrating mode, the outer ends of the fixed roller and the floatable roller are provided with openings serving as discharge openings, a swinging frame capable of swinging is hinged to the supporting frame, the blocking frame of the floatable roller and a power mechanism are connected to the swinging frame, the supporting frame is provided with a limiting reset device, the supporting frame isconnected with scraper frames which are located in the fixed roller and the floatable roller respectively, scrapers which are arranged towards the inner walls of the fixed roller and the floatable roller are connected to the scraper frames, and the edges of the scrapers are close to the inner walls of the positions, close to each other, of the fixed roller and the floatable roller. The equipmenthas the advantages that the forming quality of ceramsite is high, and rigid extrusion can be avoided, so that the equipment can be effectively protected.

Description

technical field [0001] The invention relates to a high-efficiency pelletizing and granulating equipment. Background technique [0002] In order to save energy and protect the environment, construction waste, urban sludge or river bottom sludge are processed into building materials such as ceramsite, which fully realizes the reuse of waste and turns waste into treasure. [0003] The existing ceramsite molding machine adopts a double-roller structure, that is, two rollers of the same size and opposite directions are used, and the rollers are driven to rotate through a power mechanism, and the materials are put between the two rollers. The outer surfaces of the rollers correspond to There are grooves, and the material is extruded into the corresponding two grooves through the extrusion of two rollers, thus forming a complete ceramsite. The double-roller granulator with this structure has the following disadvantages: First, it is formed by the surface of the roller, which is pr...

AI Technical Summary

Problems solved by technology

The double-roller granulator with this structure has the following disadvantages: First, it is formed by the surface of the roller, which is prone to defects such as insufficient forming or the ceramsite cannot escape from the groove, so the forming quality is poor; secondly, although the materials are magnetically separated before being put into However, it is inevitable that there are metal materials or other rigid materials that are difficult to extrude in the material, so rigid extrusion is likely to cause damage to the drum, which increases the maintenance cost of the equipment.
